BuckBoost Converter
to Drive a Single LED from 1
LiIon or 3 Alkaline
Batteries
The NCP5030 is a fixed frequency PWM buckboost converter
optimized for constant current applications such as driving
highpowered white LED. The buckboost is implemented in an
Hbridge topology and has an adaptive architecture where it operates
in one of three modes: boost, buckboost, or buck depending on the
input and output voltage condition. This device has been designed
with highefficiency for use in portable applications and is capable
of driving in DC up to 900 mA into a high power LED for flashlight /
torch applications. To protect the device cyclebycycle current
limiting and a thermal shutdown circuit have been incorporated as
well as output overvoltage protection. The 700 kHz switching
frequency allows the use of a low value 4.7 H and ceramic
capacitors. The NCP5030 is housed in a low profile space efficient
3x4 mm thermally enhanced WDFN.
